Making good on a promise to reveal additional medical information after the Democratic presidential nominee’s troubling health scare Sunday morning, Hillary Clinton’s campaign released a letter from her attending physician in an attempt to quell growing concerns.

According to Fox News Channel correspondent Jennifer Griffin, the campaign publicized Dr. Lisa Bardack’s brief note “outlining what tests have been done for [Clinton’s] pneumonia and what the outcome of those tests and recent physicals are.”

The letter released on Wednesday, a day before Clinton is scheduled to return to the campaign trail, revealed the former first lady received a CT scan last Friday.
